Introduction

The purpose of this report, prepared by the Pan American Health Organization, is to document progress in vaccination coverage against COVID-19 in Barbados.

The data presented below are provided by the country or are extracted from their reports published on their official sites (see References). The data analyzed comes from the consolidation of vaccines administered since the country began vaccination against COVID-19, incorporating variables that allow deepening the coverage analysis.

The differences between countries regarding the vaccines used and the defined schedules lead to presenting the data considering single doses and first doses (consolidated under the category “At Least One Dose”), as well as the final dose of the primary schedule (in schedules with more than one dose). Those countries that have started booster/additional doses are also reflected in this report.

Country Information

Demographics

Demographic data for Barbados is shown below, based on the UN population for 2021 and projections from the US Census Bureau for countries with 100,000 or fewer inhabitants [1]. It is important to note that these population denominators are used throughout the document for the calculation of coverage percentages.

Geographic Location

Historical Vaccinations

Historical Doses

From the start of vaccination to the date of this report, a total of 363,560 doses of vaccines against COVID-19 have been administered in Barbados [2].

Monthly Uptake

Monthly uptake reflects the coverage and additional dose increase on a per-month basis in Barbados [2]. Percentages are taken with respect to [1].

Last Week Cumulative Vaccinations

The number of accumulated administered doses up to week 23 of the year 2022 in Barbados are shown below, differentiating according to the schedules offered (e.g. completed primary series and additional/booster doses) [2]. Note that not all countries have information on ‘Single Dose’ since they have not purchased single-dose vaccines, or it is not possible to disaggregate the information. Similarly, not all countries may have introduced additional/booster doses for their population.

Coverage

The following graph shows the progress of vaccination coverage against COVID-19 in Barbados [1] [2]. Data are analyzed at the national level, considering at least one dose and complete primary series with booster/additional doses. In addition, the dropout rate was incorporated, which allows evaluating adherence to the immunization process, that is, what percentage of those who received a first dose against COVID-19 completed the primary vaccination schedule established in the country.

  • Please note that Dropout Rate is calculated as: (first_doses - last_doses) / first_doses * 100, where first_doses and last_doses refer, respectively, to the first and last dose of the primary vaccination schedule, disregarding single-dose vaccines.

Risk Group Vaccinations Summary

The following table shows the total doses administered at the national level, differentiated by risk group. Only the information available is presented, although it is possible that not all the target groups defined by the country are reflected.

Age

The following graph shows the progress of coverage grouped by age and differentiated by dose [3], which allows us to observe the percentage of the population with at least one dose and those who have a complete schedule for the primary series. The horizontal dashed line represents the national vaccination coverage with complete primary series. It is important to consider that the age groups given by each country are dissimilar.

Gender

The following graph shows the progress of vaccination at the national level differentiated by gender [4], the analysis considers only the complete primary schedule.
